The poster can just subscribed to the 50 Euro cable package. That is the legal way to get it. The poster just won't pay the list price.
It isn't impossible to watch by any stretch of the imagination. There just isn't a willingness to pay.
Just to note that in many cases the cable package is not equivalent to getting F1 TV or MLB TV to take two examples I have experience with. Both those lets you watch the events after the fact which many cable packages do not.
Not just that... the "good" F1TV package gives you many many many streams.
At least 30 or so...in-car from every single car, the main broadcast feed, and a number of others, including alternate (and generally far better... commentary)
