Please take the following reflections as my personal take on the matter, not as the official team's opinion (we have VERY different ideas on this).
At least according to Patreon's official philosophy, pledgers are not investors who are paying for a determined product (that's the difference with a kickstarter) but supporters who are backing a creator they believe into (precisely because the want to safeguard, and not limit, his artistic freedom). Something more similar to a liberal patronage of the arts (as the very name hints) than a stock sharing business. Before I started collaborating with MrDots, I had been pledging to various creators on Patreon for years, and I've always seen it that way; never tried to influence the people I was backing. That's also, btw, the reason why pirate sites like this one do not bother me too much: I'm not paying for a product (hence I do not get angry if other people get it), I'm paying to provide somebody with the freedom he/she needs to create that product, and that's enough for me. If your model is the local bowling, my model is George Martin's Game of Thrones. In one case, investors have all the rights to determine the future of the company; in the other, fans cannot presume to call the shots just because they bought some books.
Then again, the two approaches tend naturally to overlap and their confines to blur: many people do see the whole issue as you do, and I can readily admit that my view is quite idealistic and dangerously bordering on naive (Patreon itself is obviously a capitalistic enterprise set up for profit). And still, I strongly believe you always have some room for manoeuvre, without ever being completely overdetermind by "free market" rules. Akabur for example is a creator who fully shares my ideas (i.e., he couldn't care less for polls, is very wary of fans trying to condition his artistic process, etc.) and manages to run a successful Patreon page nonetheless. But he is an exception under many respects. MrDots, on the other hand, is VERY attentive to his patrons' opinions/expectations, and always tries to meet them. Up to a certain point, he does consider his backers as investors who can "call the shots" - and that's probably good for business (I guess we are lucky I'm not the boss XD). For the very same reason though, he scarcely cares (I suspect) for what people might say on a pirate board: all his consideraton goes to his backers - which makes perfectly sense, once you consider them as investors.
All in all, I'd say that the best thing to do is trying to balance the two approaches, constantly keeping in mind that every project on patreon is BOTH a for-profit enterprise and a creative endeavour.
