Earlier quoted context omitted.
Actually, I would be more confident working with a GPL- or AGPL-licensed product, because enhancements are more likely to go back upstream.
That is right. I just know, that many companies flee from GPL licenses (and more so AGPL). They omit any product involving GPL just to be sure not to get any juristic hassles (if rational or not). Here is the culprit: When no other people invest in enhancements, there is also nothing that can go back upstream. I like free software very much, but I also don't want to be forced to give things free, that I make. Problem…
That's a feature, not a bug. If I release free software and you are unable or unwilling to play fair, I don't __want__ you to use my software.
