Re: Opportunist litigation.
every SIM card used in a GSM gateway was a breach of the T&C’s and explicitly not allowed
But that's a contractual matter between the litigants and the mobile network operators. This case is about a government minister explicitly "outlawing" their business even though the law as laid down by parliament says otherwise (according to the litigants).
I think that if you had a business that was legal, regardless of what anyone thought of it, you'd be a bit peed off if a government minister "just killed it" by signing a letter ordering a regulator to change the rules.
