While it's very understandable to be mad because of the server issues, it's obviously not on purpose.
There's a lot of things going on right now and I'm pretty sure TW did not plan to upset its loyal playerbase. It's just not at all in their interest, even if it would save them a couple of bucks. Like you said, the servers have been paid for and supported for the last ten years. Do you really think they would pull out server support in the last week? Do you realize how little money that saves them? Most probable cause is just server issues due to coronavirus troubles.
Hope this clears it up a little. Keep it cool & stay at home.
