>Buy a company, drastically reduce unnecessary expenses.

This famously works out very well for PE firms.

It seems very naive to assume Twitter was casually spending 1B/yr in "unnecessary expenses". Maybe the previous CEO/CTO was a baffling moron, but I tend to have more faith in people absent of evidence otherwise. I'm going to be surprised if Twitter is around in year - I'm just they have the capital to keep the lights on but it will be a very different story if advertisers start to abandon the platform because the adops infrastructure was gutted as an "unnecessary expense".
