Unfortunately there's some truth to what Invision says like the slow development and missing user features that people want, but I don't agree that it's dated. In fact, comparing the forum module of Invision to XF, XF comes out ahead, so XF does forums better and it works very well on my iPhone.
I agree that contrary to their claims, they
do find XF to be a competitor, since a lot of those extra features aren't needed and the software is just too expensive for the average person, given its business pricing.
To emphasize the point of it being overly expensive, just look at how much Microsoft 365 (previously Offce 365) costs. For around £55 a year you get a whole suite of apps, plus 1TB of cloud storage. That's a helluva lot more product, especially that storage which requires expensive data centres, for a
waaay smaller price. One could argue that this is due to economies of scale and I'm certain that's a factor, but I don't think it fully explains it.
A company that talks that way in public about their competitors talks the same way in private about their customers.
Oh, that's an inconvenient truth, isn't it? Well said.
Finally, I hate the fact that they removed post numbers and refuse to put them back, even as an ACP option, citing issues with renumbering when posts get deleted and that they're allegedly generally not needed. I beg to differ and in fact, it's a showstopper for me to using their software.
One of the devs even created an add-on once to bring them back, but then it was pulled due to their stupid ideology. I think it's obnoxious to pull such a simple feature and not offer it as an option, especially when their software costs so much money.
