This is exactly what happened to Teamspeak, they sat on their arses for ages without changing much of anything. Now it's hard to imagine them getting back any major market share in popular communities ever again. That seems like a death sentence for a social application.

There's a difference between "sitting on their arses" and "trying to grab every single customer possible".

TeamSpeak didn't bother to acknowledge that a lot of people often just want to write some messages to others without actually hopping into a channel/server, let alone a VoIP-channel. Their synchronous-only communication philosophy via community-maintained servers just didn't pan out.

Let's not rewrite history and pretend that Teamspeak was always terrible. Their "philosophy" panned out for a long time and made them kings of the space, but to reiterate the GP's comment: things change. Now users want more convenience. Now they want better mobile support. Now they want GIFs and reactions.

You can point out what Teamspeak didn't acknowledge as much as you like, anything is obvious in hindsight. To see what you're missing, you need to explore more and more possibilities and constantly innovate. You can bet that your current or future competition is. Prescience is not a business strategy.
