It is suicidal only if there's a way to get caught. also, the full picture of the finances involved isn't always clear – the vpn business may be just a front for some other much more profitable shady business.

Besides, post Snowden, it is silly to still believe in such claims as non-logging. there are many high probability possibilities:

– it is a legitimate business but a secret court order compelled it to install a tap and feed it to secret government agency.

- its not a real business but actually a secret govt security agency's slush fund funded cyber intelligence warfare operation.

- its an unscrupulous mafia funded business running a massive hacking/blackmail operation masquerading as a business.

- its an unscrupulous shady business that's harvesting and selling your personal data to black market data brokers.

...so on. possibilities are endless.
