The donation option was temporarily suspended, due to the system previously requiring manual activation for a while. The manual system demanded too much manual labor in sorting out token issues to continue on that system, so it was temporarily disabled while they were awaiting tweaks from the management's end to make the system automated again; which it is now, therefore donations are being accepted for the project again. The token activation is instantaneous now if you do choose to donate.
A more verbose rundown on this information can be found in the actual announcement threads regarding this:
