I think some people still don't get it.
I'm saying that if the screen is changed so that it isn't techie and more clear, "Hey, you don't have to install this" (I like the WITH and WITHOUT method, very clear, GOOGLE also has one "Read this, it isn't the usual mumbo-jumbo" or something like that") more people are going to keep and reccommend Plus! which means more Plus! users.
If if most Plus! users allowed even SOME ads, I'm sure that would drastically increase the ad volume. I'll bet that most of us here don't have the ad thingy installed, because we can't turn it off. Sure, turn it on full blast at night, let a few in turing the day, as long as I can control it. Also, it might still be appropriate and professional to ask them to install WITH the sponsor under the clear understanding that it is easy to turn off and they will be in control. I have seen programs that ask you to install it to support them.
The point ladies and gents, is marketing: Make the sponsor not annoying, easy to get rid of if you don't want it (not a full un-install), and easy to adjust so that they will be comfortable with it. The point of good marketing is more money. Unless Patchou's argreement with the sponsor won't allow such changes or unless the sponsor is only ever going to pay a fixed amount, it is a good idea. Even if the sponsor was going to be like that, it makes sense to do, because eventually, someone else would be willing to pay more than the current sponsor for so much willing ad space.
