Verified. ProtonMail received no additional requests for money. And, those are the attackers' words. The original attackers claim they stopped. They hit many other Swiss companies and stopped after they were paid, as well. They are screwed now (and seem to be panicking a bit) because the size of the secondary attack was enough to knock a portion of Swiss internet infrastructure off line, anger some high profile businesses (including banks), anger the Swiss Government, and cause the matter to become a high profile case for Europol.
