I would assume TimescaleDb only sues if you money. In this case you can also afford a commercial license. If you hit big just contact them and tell there was a problem having a correct license earlier and you want to fix the situation.
There is 0% chance Timescale would sue mom’n’pop operation for breaking their license.
Your assumptions are based on good faith, and businesses are not run on that :) Imagine Oracle or IBM bought Timescale; that 0% chance suddenly increases dramatically.
