I have the same problem with Purism, it seems to me the thing is driven by marketoids and not engineers.

With Neo900 there is strong, reality-based evidence on what the team is doing, there are detailed schematics available of the bloody box down to the tiniest pull-up resistor.

With Purism there is just hyped-up words, there is no meat in the soup they are serving to you...

I don't trus marketoids, never have even though I have sometimes worked with them. They are only second to corporate IP lawyers on my list. There is an old saying describing some people that I can say for sure applies to all marketing teams, even to those in the companies I have worked for;
