Companies should be transparent about the data they collect and how they anonymize it – and should be easily disabled if needed if you need serious privacy, as is possible that some resourceful actor could de-anonymize the information somehow. But this kind of data is not necessarily harmful.
People disabling telemetry will often be the same ones complaining about "poorly written applications and company X should know better". Well they don't because you disabled telemetry, now the company or organization has no data to improve anything, be it performance, crashes or even UI. Bug reports are not enough.
