Seriously they have to? Isn't this obvious enough? When downloading TEST RELEASE you willingly accept that it will collect anonymous data and send it to them. If you do not want to test something, because you're opposed to it, do not do it.
A lot of companies do that and I do not see anyone complaining about it for example Apple and macOS betas.
