Do remember, when projects reach 1000, they can sometimes take off, frequently because they can be easily found. In this situation, it could reach 10,000 well before the LR theme is over.

They probably wanted to 'can' it before 10,000 so as not to disapoint even more Cuusoo fans. It's a lot easier to annoy 1000 supporters plus a handfull of others who cannot support, then 10,000 and tell them no.
