How many places show a difference in their prices? How often to restaurants, stores, and other as a service companies doing that? I almost never see it. I wouldn't say they are doing something deliberate (in a negative sense). They are doing something pretty typical.
They have a table of everything listed along with a new price for it. All they would need to add is a column showing the existing price. There is a 100% chance they have a spreadsheet internally passed around with that existing price column.
Do you really believe it was a not a deliberate choice to not show the side by side comparison?
Restaurants and stores are single transactions, not ongoing subscription services.
DigitalOcean makes you dig for the price increase, which is pretty scummy. They tried to soften the blow with a new droplet which looks even worse. At the end of the day, 20% is a huge change.
