IBM is certainly a dinosaur company, held up by ancient mega-customers, debt and sticky tacky. Under the shadow of whatever marketing budget they have left, they're probably under some legacy mode enterprise life support ... but .. they still massively influence the entire Linux landscape via Redhat and Pottering (although looking it up, seems he left for Microsoft ... so oddly enough, MS, IBM, Intel and other big tech all contribute monetarily to a significant piece of Linux development).

But as far as my original question, yes I know Firefox has dropped from 1/3 of market share to next to nothing. That's not what I was getting at. There are still developers, paid for by Mozilla, who continue work on Firefox. Who are they? Where are they going to go? Will they continue to work on the core rendering engine, paid for by some other means? Will they give up and move on? Will there be 12 forks and a lot of shitty browsers for a while by people trying to keep up but barely can wrap their heads around that massive Gecko codebase, before distilling into 1 or 2 usable and maintained versions? (Honestly, not too unlike the original Netscape->Mozilla in the 2000s).

We already lost Trident (when Edge moved to Chrome/Blink) and I wish Microsoft had at least open sourced it. I've compiled some of the early builds of Ladybird and it looks promising, but will it be enough to prevent the collapse of true browser engine choice?
