You proposed a change to a repo you do not own. You offered an incentive to 3rd party developers to push PRs to that repo. You did not wait until the proposal was accepted. You thus required the community maintaining that repo to do extra review work on a feature they hadn't officially accepted yet. You were refused, and then offered the same incentives somewhere else, with the same drawbacks on the zig community.
Even in your new offer it's unclear whether people should make changes in zig (add support for your features in zig) or in wasmer (change the samples to work with the current zig compiler, or build libraries that work with zig) to support your features.
There's a time and place to offer incentives for someone else's project, but that shouldn't happen without their approval.
