A few of the top contributors are the one behind the company. It is fair to assume they are perfectly ok with stealing from the community as it directly benefits them...
The people doing all the work are "stealing" from the "community" that contributes much less? If someone wants to fork here, it seems like they would also need to step up the amount of contributions they're doing if the people currently doing the work are the ones organizing a way to make some money to pay for their time.
Or I mean even Gitea has been on the other side of this, while the Gitea contributors _were_ gogs contributors pre-fork, they were not the largest.
2. The reassurance that Gitea would be a stable platform to build on without having to compromise between the open source project and a commercial variant
This open letter had to be published even if it has little chance to be effective. It would be horribly wrong for something like that to happen in a Free Software project without offering a simple and gentle way to do right.
Ultimately it is quite possible the only solution will be a fork. And as the Gogs fork showed, it only takes a handful of motivated developers to succeed.
