"I’ve been a big fan of Hetzner. Unfortunately they’ve made a feeble attempt to dress this change up in the name of “fairness”."
Hetzner is a company know for it's precise pricing structure. An increase in prices would be correlated to an increase in costs, and in fact the next paragraph Hetzner writes:
"With the new tariff structure, we want to make conditions for our customers around the world as fair as possible "
Bottom line, the US imposes tariffs, this increases the prices of imported products, of which Hertzner is one, (Servers from Europe)
How can you write an entire article to complain about a price increase and not see that it was actually your country that increased the price.
