When a vendor wants to control upstreaming process and objects to community-led patches, I’ll just point to this brilliant response from @conor:
It’s only better if <vendor name> submits better quality patches (no evidence for that yet) or submits the patches more promptly than others (which clearly has not happened here), and offers review commentary etc at a higher standard and more frequently than a non-employee maintainer would be able to do (there’s no evidence for that so far either, given you’re trying to stall this patchset). Your claim seems to have no merit as there is no proof that you’d do a better job.
