It's not too terribly unreasonable. It's largely the Linux Foundation trying to wrest control over chromium from Google before the FTC antitrusts them or before Google does more manipulative market controlling BS.

In more polite terms they are framing themselves as an ideal long term steward for the chromium project given that courts have already ruled that Google isn't a suitable steward anymore. Chromium wouldn't be so problematic if it wasn't run by such an anticompetitive organisation. If the Linux Foundation ran chromium and orgs like Igalia (who already do a near majority of the dev work for chromiumm) took over the brunt of senior development and leadership control then it'd be a pretty solid technology stack (albeit with some weaknesses).

I personally prefer Firefox and it's associated technologies but I also acknowledge the appeal of Chromium distributions like Vanadium.
