In 2017 I paid 550$ for this:
Now it's increased near 50%, the renewal went from 190$ to 280$ / year.
For me, the price increase is still bearable, as long as my income from the forum does not drop significantly. But for hobby communities, such prices are probably harder to bear. By the way, these hobbyists are free advertising media for Invision, as they promote their product. Ultimately, new forum operators orientate themselves on the platforms in which they themselves are active. If they disappear from the market, this advertising also disappears. Another very important aspect is the existing add-ons of a forum platform provider, these are and always have been a driving force for a successful community, see vBulletin. Some developers have already spoken out about the price increases. If this price increase causes them to turn away from Invision, this will also lead to lower licence sales in the long term. So this new development could lead to a downward spiral.
I don't understand why developers as important as openfont and Adriano have to pay licence fees at all, because without them Invision would certainly not be where it is now. Without developers, without high quality addons, no customers, to put it bluntly. Just because of a few hundred dollars more revenue you risk losing everything you have built up over the years. This is not a wise decision because the developers are the be-all and end-all of any successful forum platform.
