If that type of thing annoys you then you should restrict your use of open source projects to those backed by corporations with a paid support business model.

Not really no, you got the support you were willing to pay for.

Is that a serious question? It works like any contract programming gig. You give the contractor money and in exchange they give you code (including copyright assignment). You can go through a freelancer site like Upwork if you don't know an appropriate contractor yourself.
