The opening line follows the boilerplate trend of acquisition posts. Being acqui-hired is not something that you should be celebrating with your users... PERIOD. (On a side note, I'm genuinely happy for you all. Getting paid isn't a negative. It's a huge opportunity, but don't patronise your users).
"Yey us. :D We're super excited to announce we got acquired. High-five... too slow... Now go f* yourselves."
It's incredibly condescending to assume that any of your users share your happiness and are apart of this experience...
"We’re really excited..."
You use "we" so many times as if your users are apart of your acqui-hire, yet only mention "you" (your users who made this possible) in the closing statement.
Be honest and graceful, but asking your users for a high five on the way out isn't the way to do it.
PS. I hate posting negative comments. I'm a Brit, and like to be polite all the time....
EDIT: Call me out on this if you think I'm wrong. Other people who have read it think I'm just reading into it way too much. I tend to agree that I'm particular, and it could easily be chalked down to me being overly zealous to criticize another successful acqui-hire. :)
