tl;dr: after pushing rcs so hard for years, killing hangouts well after forgetting about it, & hiding it from gmail, google now wants you to use its (and google allo’s) successor, google chat.
Yeah, I hit a point around 2018 where I went from being a huge fan of Google’s to switching to iOS and trying to degoogle my life as much as possible (but also not wholly relying on one company for anything. I still have Google photos, but I also have local backups of all my photos, plus they’re in OneDrive and iCloud for example)
