Let me get ahead of you there. They would only pay for a quality product which Twitter is definitely not, as a ruiner of modern discourse. Of course there's also the catch that there are no quality products anymore. The whole world of products is devolving at almost the speed of Google Search. But definitely paying is the superior business model
Bootstrap comes to mind - and while that's not something I foresee them "selling", a company large enough to produce a F/OSS project of that size and complexity surely has any number of large, mature products that they could sell or monetize.
Also, the key part of the LBO playbook isn't making quick cash from selling off assets - it's divesting the company of cost centers and investing heavily in profit centers. If you're able to sell the things that aren't making you money, all the better.
