Whatever investment they had made in them literally evaporated in a week as mariadb and galera showed up. OpenIndiana basically made continued solaris development at Oracle a moot point, not that it wasnt already with Linux on the scene.
RedHat has tried something similar with CentOS, Encumbering it to try and drive sales, which backfired just as predictably. Rocky is a treat to run.
Rolling up Android into a proprietary walled garden would be a disaster. This isnt apple. What you could expect is a massive developer exodus from the open community to other friendlier projects. If your interest is western security/hegemony in technology then it would be a shame to see all that intellectual capital suddenly captured by a FOSS project from a marxist leninist country thats all too happy to give it away for free (DeepSeek anyone?)
