Well, let's look at it more realistically.
The client is a few years old. Since 2016, I believe. Season 6. It's not 10 years, it's...3? 4? Idk, math is hard. Either way, less than 10. Not even half of 10, for certain.
And, you know, they have fixed bugs in it. If you remember the first days of this client, it was actually really buggy and slow.
The fact that there have been bugs since its release does not mean bugs aren't fixed. That could be a meaning in some cases, but it's pretty clearly not the case in this one. This is just new bugs coming up.
Yeah, it's kinda dumb that it's had bugs since it's release. The new bugs coming up for seemingly no reason is also pretty dumb (But that does imply backend work to try to do something else. Maybe fixing another bug? Maybe implementing something? Either way, something is happening to cause them). But saying they're not fixing them is not the truth in the slightest.
