Your assumption that cloud service providers can perpetually absorb increasing costs is not one I share.
I would further contend that the price is not the highest level it can be. It's kept at a rate that's competitive with alternatives, while still allowing a return on investment.
If that return on investment falls then the investment funds will be redirected, to where a better return to risk ratio is possible.
Thus if costs go up (due to criminality) either prices rise or investment falls (leading to a reduction in services available). Either of those options is a poor outcome for non-criminal cloud users.
You don't have to believe me. The article includes the views of industry experts. You're welcome to provide evidence that they're wrong - if you can find any.
