This forum is the place to talk about all things that are concerning to partners, agencies and freelancers that build sites for others. That includes technology challenges we are facing. Not all conversations need to be based on Wix, either.
Wix has challenges - no doubt, and there are some great ways to discuss that. Pointing out the limitations of Wix by consistently using marketing lingo from competitor sites is probably not the right way to do it. It also isn’t advisable to respond to every comment with a link to a competitor and encourage members to “go there and try out xxx”.
I will never shy away from a difficult conversation, but there is, just like all things in life, the right way to approach it.
