I know a couple of apps that could have that for strategy so I completely understand the question ;)
We have absolutely no plan on doing that, even for anonymized data. The only use of this data is for the application's purposes and to be honest if we could bring the same value with End to end encryption, we would do it.
The reason for not doing it is simple : we have a much simpler business model, Slite actually provides way enough value for active teams to start paying and that's enough to focus on ;)
