They are asking you to update software...
888 is a sportsbook and casino that offers a poker client, obviously they are going to try and nudge you towards their most profitable product. If you don't like how they conduct business you can boycott them and use none of their platforms but I don't know why it would be the government's responsibility to prevent a company from promoting a LEGAL product in your country because you don't like it.
There's also always the self-exclude button. If you self excluded from the casino and then you got this "request" that would actually be dodgy and I'd take your side
