I can tell you from our experience with Stormpulse that this is 100% false and backwards. Those that pay more are more willing to work with you. Nothing more expensive than someone that expects the world for $10.
Maybe it's not that they pay more that makes them more likely to work with you, but rather there's something about people who have more money to spend (ex Enterprise-level customers) that changes their awareness of the realities of the solutions they buy.
They are convinced of the value and therefore less likely to abandon the product because of one negative. Whereas if you aren't sure the app is really doing something for you (making/saving you money), you're more likely to bail and just get your money back the moment it goes
South.
