As most who's ever worked with web hosting can confirm, small business customers often have no idea of what they're doing, and I've talked to many people who switched providers after seeing an ad for cheap hosting, without realising that they have to a) wait for the DNS changes to propagate, b) that they have to actually move their web site from one provider to another.

Subsequently, my previous employer lowered the default TTL simply because it got rid of all the bad Trustpilot ratings about customers being "prevented from leaving", and started offering a "move my WordPress site for me" service to profit from all the panicking new-comers who had no idea about how to do trivial things like importing/exporting a database and transferring files.
