Silver Lake being one of Unity's largest shareholders explains their recent behavior perfectly. It's a private equity firm whose sole concern is squeezing blood out of a rock.
That's basically the reputation of a significant number of private equity firms. Their standard operating procedure is to load the company up with debt, cut R&D, cut investment into the product, cut wages and raise prices to increase short-term profits while pretending you're trying to turn around the company and save it. That's basically why Sears and K-Mart don't exist anymore[0] and why so many newspapers fired their journalists and replaced most of the local news with national news from the wire services[1].
Everything except short-term profits. X seems decently focused on the long term, especially with subscriptions being introduced as a (new) revenue stream.
Also not sure about R&D, as I don't know what R&D Twitter was doing pre-acquisition, but there's been an extraordinary increase in the rate of addition of new features and changes to the platform.
Elon's twitter acquisition was a play to sell lots of incredibly overvalued TSLA stock without tanking the price.
May a lot of noise, declare you're done with Twitter's bots and BS, sell a ton of stock -- not because it's overhyped, no it's for Twitter -- and then back out of the sale.
And he would've gotten away except he tried to back out 3 times and they held him to it. So now he's got this trainwreck situation, and he's doing what he thinks is the right play, lemons into lemonade.
