You aren't a product? Then pay for the products you use instead of asking to get it for free. If they don't give you the option to turn telemetry off in the paid product, then go ahead and complain. But pay for what you get.
I'm not conflating these two things. I didn't say they have to have telemetry to keep it free. All I am saying is, if you have the option to pay and decide whether you give them telemetry or not, then there is no reason being vocal about them giving you more for free. It is a company and they need to make profit. If more users with telemetry enabled gives them more data that they can use to indirectly increase their profit, I only applaud them. If they stopped allowing to turn telemetry off for the product in paid version as well, then you would have a valid point.
That said, nothing wrong with being vocal about privacy and high standards in collecting usage.
I wouldn't take people seriously who are vocal against telemetry in a product which has paid version with the option to turn telemetry off. Such people would be vocal against paying for the work others do. Also, if properly anonymised, telemetry isn't the devil people make it to be.
Great news. It is beyond me how people are complaining about the free version not allowing to turn off telemetry. Why don't you stick to the paid version if you are bothered by the (anonymous) telemetry?
