While your argument is valid and your choice is too. I don't think your threat will work that well getting the gallery changed to the way you want it quicker than it would if you didn't threaten. They have lots and lots of clients. I'm sure they wouldn't mind losing one as they gain lots each day.
What you should have done is requested that feature either as a hook, or added back into the gallery in a nice calm manner.
The only modification that does this hasn't been updated for 3.2 and the support topic said it's not working until the upgrade is done by the author. Having it by default would be that much easier. And maybe if there was the ability to select if it appears, or if it doesn't then that would be even better. Plus the ability to choose what groups show would be good too.
I am very pleased by the support that IPB offers. I've run forums in the past on different software's such as phpBB, MyBB and others such as SMF etc but IPB offers the best fastest support. When I was with phpBB I would have to bump my support topic a few times in some cases. IPB replies within a good time set and offers quick basic help but it allows me to get what I wanted fixed in such a way that if the same thing was asked at phpBB they would give me a very complicated answer.
IPB is the best software I've ever been able to use.
The reason why you buy IPB is because it's the best software in the world and the staff and support team always reply to tickets and topics quite quickly around here and in the client support ticket area.
Maybe there are some bugs. But the developers get to them quite quickly. And as said above if you're not too sure about IPB right now there is a cheap hosting package you can purchase to get the feeling of the software.
The show online/offline topic is the most useful thing on forums. After so many years using forums a software that doesn't show if the member is online or not in a topic it confuses me. I'm always one to look at who is online or offline. No matter the forum genre.
My understanding with the hosting is you can get a refund if you are not happy with the software. You cannot once you've downloaded the actual software get a refund as who's to say you're not going to keep it? :)
