Having a single company with most the control is not necessarily the same as having a corporate sponsorship. A language could have many corporate sponsorships and benefactors. The problem being referenced is having one benefactor with too much control. That problem is fundamental. As soon as one entity gets too much control, it's impossible to wrest control back without their agreement, or a long protracted battle which will hurt the thing being fought over. Nobody is saying keep corporate interests completely divorced, this is just a call to be aware that one interest is getting too much power, whether on purpose or just through increased interest on their part, but the end result is the same. If we care about Rust not being beholden to one entity at the expense of others, then action should be taken now (even if that action is just much increased scrutiny and asking Amazon to please make sure the executive directory position is filled ASAP, and not with someone Amazon affiliated).
