There was some wild change they wanted to push some time ago, users started mass migration away from it forcing them to abandon their insane plans.
These companies only learn when the problem hits their pocket.
I still have my social media accounts coz otherwise, hobbies and alike gets impossible to track. But I only access them via PC browser/mobile browser on my GrapheneOS phone.
Instagram only allows video upload via their app which I can understand (compression and etc), GrapheneOS allows me to lock everything so I only use it to upload videos. Man, it is a complete mess, Sponsored, Threads posts that takes you to install apps and ADs is everywhere and I mean everywhere.
On my phone/PC, nothing of the above exist. It is just one post after another with, no Ads, no sponsored, no apps, nothing. Facebook follows suit, I have not used their app in years now, mobile browser only.
WhatsApp is gonna become exactly the same, a complete mess. People accepted Instagram changes so....
