The server/login issues for a gaas game are embarrassing, doubly so for having lasted this long. The person who wrote their buggy network code should be fired. Especially since it was not tested before launch
For uninformed people and hater trolls like you:

According to the Arrowhead CEO it has somewhat similar CCU in PS5. This normally causes issue that aren't possible to predict or test internally with simulations or even in open betas. As a game CCU coun scales there are new issues that appear. It's a very difficult area for servers programmers but they are solving the issues very fast.
The amount of server issues they have are minimal, and the login one isn't really a server issue: when servers are full they prevent new users to enter to avoid a server collapse, so you can't enter until someone else leaves. They solve that by hiring more servers, which are really expensive so companies hire only a bit more than the ones they need and add or remove as needed almost daily in these kind of situations. Normally these peaks are only a few days long.
The only issue not completely fixed is the matchmaking one, even if it improved. The rest of the game has been working pretty well related to the servers.
