The UK does a lot of prosecuting people for having said nasty things online that someone else didn't like.
Hungary is far more inclined to surveil political opponents, put people in their network in jail without fair trial, surveil successful businesses whose bribes were insufficient, find excuses to punish those businesses.

Not only are there not similar reports about the UK, but its better position in international corruption rankings points to a culture that would be less likely to tolerate this.
Any further questions about why there should be concerns about how Hungary would be likely to abuse a law like this?
That link literally does not have anything to do with fair trials.
