Linux has been majority developed by large tech companies for the last 20+ years. If not for them, it would not be anywhere close to where it is today.

At the end of the day, maintaining software without being paid to do so is not generally sustainable.
Considering some of the changes to the ecosystem in the last 20 years it's not clear that this has made things better.
