There is this concept of supporting people you like without them having to charge people. The more you can read upfront, the more you can make an impartial judgement if you actually like them. A lot of people subconsciously convince themselves that they like something just because they spent money on it. If I like a project or open source software that I use then I go support the developers. A lot of other types of arrangements are basically signing a contract waiving your rights before you've even had a chance to form an opinion.
