People had throwed shit at it because of their own specific issues and its “slow” development pace without realizing it’s a titanic endeavour
I think most realize that it is a titanic endeavour and know that it might take years until their issues are solved, so they get angry when people are like “works for me, so everyone should use it now”. I’ve tried Wayland twice, each time it was deemed “ready” by someone, and each time something obvious was broken. x.org works and does what I want, so I’ll continue using that.
If you’re using a password on one site you’re trusting that site to keep that password safe, so that only you can access your account.
If you’re using one password everywhere you’re trusting the weakest site to keep your most important account safe, which is obviously a bad idea.
Your friend is trusting the weakest sites he uses (or used at any point in the past) to keep his password scheme safe. Not quite as obviously bad, but to me it doesn’t seem to be a particularly good idea either.
