Foundations don't really do maintenance on products. Electron is maintained by a few people at Slack at one or two at Microsoft. Of course if you count the Chromium codebase then it is indeed "Google's framework" and they do nearly all the maintenance.
Not sure if this is trolling but Electron is a big open-source community project NOT "maintained by few people at Slack and one or two at Microsoft", you can easily check that by going into repository insights and seeing the correct information which for the last 30 days is "25 authors have pushed 52 commits to main and 267 commits to all branches".
The Chromium take is even bolder, it is indeed NOT a "Google's framework", and it was maintained by at least 1600 authors most of whom are not from Google [1]
Most of those authors are drive-by fixers. Go scroll through the commits list and look at the affiliations of those who are doing the regular work. But watch out, a few of them list OpenJS Foundation but actually work for Microsoft.
The Chromium stats are misleading for the same reason. Almost all commits are made by Googlers. There is a long tail of contributors over the years outside of Google but that doesn't mean their contributions are equally sized.
Yes, but there are 15000 forks of the electron by individuals, even with contributions being not equal, it is still a community project owned and used by individuals and smaller groups all around the globe, not only Google or Microsoft. The same applies to Chromium. The fact that MS is the biggest maintainer now is not a coincidence because it is in their genes to constantly try to take over the good stuff to commercialize under their brand.
