I happened to click a link that took me to the associated ~~twitter~~ X account for something I was interested in and was greeted by not one, not two, but four modern day web popups.
I know it's nothing new. I've got a couple of firefox plugins that are usually quite good at hiding this sort of nonsense, but I guess they failed me today (or, I shudder to think, there were even more that were blocked, and this is what got through)
What's the worst new/not-signed-in user experience you've encountered recently?
You're right in theory, but in practice the point is that email survives because it's not a closed, proprietary protocol.
Unfortunately I don't think the issue is quite so simple. We used to have open chat protocols that were slowly strangled by big tech until only their solutions remained.
I think the biggest problem is simply user apathy, if users cared more we wouldn't have the whole US green/blue bubble problem
