I'm speculating here, but perhaps this was the root of CL suing PadMapper in the first place.
It certinaly doesn't look good for CL, IMO, if they only started working on it after PadMapper started gaining momentum.
It's an interesting question.
How did you get your numbers for your conclusion about "most perspectives"? That is not just an opinion, correct? Otherwise you might have used words like "I think" or "in my opinion".
Another related conclusion I'm curious about is "their data" (i.e. the data users uploaded is now CL's data). That is not just an opinion, correct? When I search for a clear answer on that issue, I can't find one. I'd love to see some clear guidance on this question.
Platform providers do sometimes use their advantages unfairly. But platforms cannot succeed without some level of symbiosis between those who provide them and those who use them. This is only my opinion. However I have seen others say much the same thing.
We could argue whether it is good or bad for platforms to copy a feature and push services like padmapper out, but it is still their platform. But a big guy suing a small guy, especially when he was making the service better definitely looks like bullying.
