En Statement by Xtra Manager Software :
📢 PSA: Google's Play Integrity is a Business Scam, Not Security 🔥
Yo modding fam! 👋 Just exposed Google's dirty secret about Play Integrity API.

🎭 MEETS_STRONG_INTEGRITY = Marketing Badge, NOT Higher Security
- STRONG ✓✓✓ = just means "app from Play Store"
- DEVICE ✓✓ = already FULLY SECURE (locked bootloader + verified boot)
- ZERO actual security difference!

📊 FACTS FROM OFFICIAL SOURCES:
Play Integrity API Checker repo (1nikolas/GitHub) literally admits: "app must be on Play Store for STRONG" - NOT device security requirement!
Google docs confirm: STRONG = DEVICE + "optional signals" (marketing BS)

🧠 YOU'VE BEEN PSYCHOLOGICALLY MANIPULATED:
Google named it "STRONG" to make you FEEL it's essential. It's psychological conditioning! 🪤
Truth: DEVICE ✓✓ = FULLY SECURE. STRONG just adds Play Store badge. Same security.
If you think "I need STRONG for banking": ❌ You fell for naming manipulation. Wake up! 🐑

🎪 Meanwhile, Custom ROM Users WIN:
- KernelSU/SusFS/HMAL/Shamiko/Tricky Store ✓
- Spoof bootloader + valid keybox ✓ 
- ROM signed release-keys + healthy TEE ✓
Result: STRONG ✓✓✓ on modified system! Banking apps work perfectly while Google can't tell difference 💀

🤣 SPIC & Play Integrity Checker: Apps made to CHECK integrity, forced to publish on Play Store for STRONG badge they're testing. Circular logic documented in their own README! Victims of the system they check 😔

🔒 Why DeviceChecker/Shamiko/Tricky Store/LSPosed going PRIVATE REPO:
- Public = free intel for Google's reverse engineers
- Private = survival strategy (6-12 months longer effectiveness)
- Fighting Google's monopoly warfare ⚔️

💰 Why Google does this
Force Play Store ($25+30% cut), psychological manipulation, kill custom ROM adoption.

B. developer.android.com/google/play/integrity/verdicts

DeviceChecker - my app simulates STRONG for locked bootloaders with transparent disclaimer. Honesty > Google's manipulation. Private repo because Google doesn't deserve free intel. 🖕
Don't forget to share this statement, so that the stupidity of the strong integrity issue disappears immediately.

ID statement dari Xtra Manager Software:
📢 PSA: Play Integrity Google = Penipuan Bisnis, Bukan Keamanan 🔥
Yo komunitas oprek! 👋 Gw expose rahasia kotor Google soal Play Integrity API.

🎭 MEETS_STRONG_INTEGRITY = Badge Marketing Doang
- STRONG ✓✓✓ = cuma artinya "app dari Play Store"
- DEVICE ✓✓ = sudah FULLY SECURE (bootloader locked + verified boot)
- NOL perbedaan keamanan asli!

📊 FAKTA DARI SUMBER RESMI:
Repo Play Integrity Checker (1nikolas/GitHub) NGAKU SENDIRI: "app harus di Play Store untuk STRONG" - BUKAN requirement keamanan device!
Docs Google konfirmasi: STRONG = DEVICE + "optional signals" (marketing BS)

🧠 LU KENA MANIPULASI PSIKOLOGIS:
Google namain "STRONG" sengaja biar lu MERASA itu essential. Ini psychological conditioning! 🪤

Fakta: DEVICE ✓✓ = FULLY SECURE. STRONG cuma tambah badge Play Store. Keamanan sama.
Kalau lu mikir "gue butuh STRONG buat aman": ❌ Lu kena jebakan naming. Bangun! 🐑

🎪 User Custom ROM MENANG:
- KernelSU/SusFS/HMAL/Shamiko/Tricky Store ✓
- Spoof bootloader + keybox valid ✓
- ROM signed release-keys + TEE sehat ✓
Hasil: STRONG ✓✓✓ di system modified! Banking apps jalan perfect, Google gabisa bedain 💀

🤣 SPIC & Play Integrity Checker: Apps buat CEK integrity, dipaksa publish Play Store buat STRONG badge yang mereka test. Circular logic di README mereka! Jadi korban sistem yang mereka check 😔

🔒 Kenapa DeviceChecker/Shamiko/Tricky Store/LSPosed PRIVATE REPO:
- Public = intel gratis buat reverse engineer Google
- Private = strategi survival (bertahan 6-12 bulan lebih lama)
- Fighting monopoli Google ⚔️

💰 Kenapa Google begini?
Maksa Play Store ($25+30%), manipulasi psikologis, bunuh custom ROM.

SUMBER:
A. github.com/1nikolas/play-integrity-checker-app
B. developer.android.com/google/play/integrity/verdicts

DeviceChecker - app gw simulate STRONG untuk locked bootloader + disclaimer transparan. Kejujuran > manipulasi Google. Private repo karena Google gak deserve intel gratis. 🖕

Shoutout: KernelSU/SusFS/HMAL/Shamiko/Tricky Store/LSPosed devs = Pahlawan Kebebasan! 🙏🔥
Jangan lupa statement ini di share,agar ketololan perkara strong integrity hilang seketika
