Yeah - in this context it's a pretty poorly defined term... Particularly since the original comment could be read as either " anyone on the continent (that geographers call Europe) ..." or " anyone on 'the continent' (where you get continental breakfasts instead of full English breakfasts) ... "
I'd probably rather question whether the ".eu" tld means "Europe" (in which case there's a reasonable argument to be made that UK residents should be permitted to use it even post Brexit) or if it means "European Union" (which'd mean the UK voted to opt out of being able to use it).
