Completely agree with this point. Unless you are paying for the service (by being the product or via donations) you have no particular right to get upset with the creators of said service.

Professionalism and an understanding of the impact this will have on Signal's users. Some will be cut off from necessary communication channels while others might literally have their life depended on the service working.
This very delayed response from Signal, coupled with some of the stranger behaviour of the last year and inability to host my own servers is really pushing me towards looking at Matrix as an alternative.
And for the record, I've donated to Signal for the last 3 years.
