If what you want from smartphones and apps from them is reliable system, the entire world has been only bad news for more than a decade
"Closed iOS has its own problems because of closedness - they secure the phone from non-Apple threats but take control from you so that whatever APPLE ITSELF (or approved apps for iPhone) does, it's something you are stuck with"
Then buy Android phone... (initially it was the solution)... Then all the "features" came - ADB becoming no longer a tool but something existing only as formality "it does exist, yes" but no longer promising any backup (only at will of app vendor). Try to downgrade app version to get rid of the flags of newer version? OS refuses it...
Maybe make your own version with far higher "number of version" that has no WhatsApp functionality at all? Just absence of app the flags that guard app data? Again... signature mismatch...
(Never argue with fans of such system unless you are willing to become highly annoyed by the same responses - "It's not a bug but a feature")
Downloading backup from Google Drive? Sorry, regardless of you paying for Google Drive, still it's what only app is allowed to access, not you.
WhatsApp itself? The desktop version having become useless as opposed to what it used to be...
Governments contribute to such situations either. India with 6-hours logout period without constant confirmation of same SIM being active. Who can rule out that other governments are going to do the same?
