I don’t find sketchup free particularly useful to me, but I have worked with it enough to answer questions and know it is developing all the time.
I know nothing about sketchup shop because I’m not going to subscribe to it just so I can answer questions on how it works.
I’ve never defended or attacked Layout because the only times I have every used it were to work out how it worked so I could explain to someone how it worked.
On the other hand I have worked with the forum/team by finding bugs, making feature requests, solving issues, helping others and generally being positive. Occasionally I have been less than positive but I have mostly done that behind closed doors.
While others only find the time to be negative.
I know which I find most productive.
