Whilst we can still get Gift Aid declarations (HMRC have previously confirmed this was ok) we should probably add a caveat on the form explaining that our charitable status is contested.

And one from the email from HMRC:

Wiki UK Ltd is not established for charitable purposes only as required by the legislation and so is not a charity for tax purposes. The charity tax examptions and reliefs (including Gift Aid tax relief) are not, therefore, available to Wiki UK Ltd.

I think you would be on dangerous ground using Gift Aid at all.
