A key point is that Kagi raised its prices already so it was sustainable. The reason most services get worse is because they are downright unprofitable and it is impossible to get them there without either making them drastically worse, or raising prices, which free sites can't do. Kagi has already put itself on a path where it doesn't have to make itself worse to cover its expenses, because it is already covering them.
