What turns me off about NextJS is its "opt-out" telemetry. You have to do a bit of magic at the system level "npx next telemetry disable" to turn it off (which you can only figure out by an internet search). This seems very disingenuous on part of Vercel. Make it an "opt-in" or don't fricking track. Conduct a yearly survey or use some other means if you are so interested in improving the framework. I am open to other…
There are major OSS projects with no telemetry that are hamstrung by their lack of insight about which platforms and systems their software is running on.
Everyone should have the right to turn it off, but I think this is going to become the norm.
