I'm not confident this will lead to industry-wide trends, at least not immediately, because Twitter is specifically a massive company making negative profit. If Twitter was profitable, then this entire thing wouldn't have happened; they need to get lean because they're losing $$.
In my eyes, this is not TOO much different than the kind of radical reorg that might take place at a company like Twitter anyway (although ofc I've never seen it first-hand), just weird that it's playing out entirely in public.
That said, I think the public strategy is potentially interesting, as the engineers who remain at the company will probably feel like they're a part of a very exciting moment, will feel more aligned with leadership, etc.
