The final choice is yours. The choice to use or not use Kunena is your choice; the choice of webhosting provider is yours, too. It's the same choice with any kind of website that people may consider: what software do you need and will my webhosting provider be able to run it?

It is not our responsibility to tell you what to do any more than it's our responsibility to tell your webhosting provider what they must do, either.

These are the established facts in the matter. You have had this problem for over 2 months and there has been no resolution offered by your webhosting provider. You do not have this problem if you use a differently hosted platform. From what we can tell, no other person has reported this problem with the Kunena Latest module.

I think those facts speak for themselves. We have offered you the best advice that we can under these circumstances. In the end, the choice is yours. You have to choose the best solution that works so that you have the kind of website that you need for your purposes. I can't advise you any better than that, sorry. For your sake I will ask the Kunena developers to look again at this topic to see if there's something we've overlooked but, I caution you, this could take some time and it may only delay the inevitable, i.e. we may not be able to fix this problem for you where it involves your current webhost.
