I'd be careful about reading too much into the results of that poll, or the number of upvotes on the github issue. The people who disagree with you are far more incentivized to vote than those who agree as well as those who are neutral.
The only reason I am hesitating is that I fear to confuse more people than I help. If people (including myself) would know what (actually had to look up the term again) "source-available" means I would have used it from the start. But nobody does. So the question is, is it worth confusing a big group of none-vocal-people to make a small group of vocal-people happy? But I can understand definitely understand their point. So have to decide on that the next days.
