Plenty of businesses are happy to block 20% of real customers to decrease fraud rates by 80%.
Especially low margin businesses, where you might have revenue of $20 in a transaction, but a profit margin of just $0.20, fraud is really painful if you lose the complete $19.80. You're happy to turn away a lot of custom to avoid some fraud.
Classic example: Bank loans. They might only earn 1% of the principle, so a fraudster who runs away with the whole principle has to be really rare.

It's also a volume question. If you have low margins but high volumes, you might run a very sophisticated anti-fraud setup to walk the razor thin line around compliant chargeback and refund rates. From the consumer POV of course it's all the same and annoying at that. But the plumbing behind the system has some insane blunt tools, some programs held together by excel-sheets and duct tape while others are super complex with blackbox rulesets.
