I saw this two weeks ago. I had a few days where I thought I was going crazy because there was no “log in” link in the header, just a more obnoxious “open the app” button instead. After a few days I did see the log in button again, but I had already accepted the fact that I’d only be allowed to use their mobile app and convinced myself I’d close my account (which I subsequently did two weeks later)
I remember this and thought I was crazy. There was an article linked somewhere on Lemmy last week that addressed this. It seemed like it was a Steve Jobs special - no one knew he was going to promise that. Subsequently, they got tangled up in a patent dispute with someone who owned a very vague communications protocol patent. That outcome has been appealed, from both sides, in courts basically since then.
