Which I'd understand, but think they are throwing too much away in pursuit of too little. Still it's how they'll try and dodge. Well, that or "we don't need human rights anyway, can't make us, so neener neener."
There is still a bit of a jump (how did they know who to wiretap? It wasn't really reported, afaik), but looking at the biographies of involved parties, they're the sort of people who would have been prime suspects anyway, so choosing to bug them was probably not an improbable decision to take.

Mass Surveillance will grow in response, as the uk's logic will be that it's necessary because Europe don't do it.

Unrelated, but it shows that the UK courts care about ECHR rulings. And the standing thing usually happens in the US, not in Europe. European courts rule a lot more on "principle" of doing something, and it matters less if the people accusing the state were involved or not. What matters is evidence that the government did or didn't do something (like mass spying), not whether John Doe was affected by it.
If mass spying is illegal under the European human rights laws, and the governments are found to have engaged in it then the only possible outcome is that they broke the law. Why should it matter if it affected this guy or that guy?
I really think the "no standing" excuse is a very poor one, as it effectively guarantees people have no redress against secret spying against them. That's not what a democratic country should be allowing.
There needs to be judicial redress for everything. Heck, I think the US is about to pass a law that gives EU citizens/foreigners judicial redress against US spying, but the Americans still won't get that. It just goes to show it is possible to have redress, it's just the powers that be don't want you to have it.
