I completely agree with you. As a TeamSpeak user since TS1 (2001), I feel absolutely betrayed and misled.
It’s painfully obvious that artificial limitations are being used to push their own hosting services to the forefront in order to generate more revenue. There’s a clear attempt to deceive self-hosters and gradually force them into using TeamSpeak’s official hosting.
This is already evident from this post (TS6 BETA | Community Update & Insights), where they promote the 64-slot servers in their own hosting while claiming to “listen to the community.” But when you ask why the beta server is limited to 5 slots, there’s no real answer—just evasive statements.
TeamSpeak is dead. The developers are trying to troll us with a rebranded TS3 server while luring us into their own hosting model.
