>While I do believe that selling to DigitalOcean was a mistake ultimately

using the word "ultimately" makes this "Monday night quarterbacking"

It's not a mistake to plan a picnic for a day that turns out to be rainy, even if you got paid to plan the picnic.

It would be a mistake to sell if the seller should have known at the time of the sale that the seller's goals would not be met, but something turning out badly doesn't retroactively make it having been a mistake, it just means it came out badly.
