Those are good reasons to choose BorgBackup over Tarsnap, but they aren't related to your original claim about pricing. There are two questions here:

1. What are the benefits and market size of Tarsnap compared to other backup solutions like BorgBackup + GCP?

2. Would Tarsnap make more profit it it raised its prices?

We seem to be arguing about question 1, but Patrick's advice to Colin is about question 2. Earlier you pointed out that Tarsnap is 25 times more expensive than GCP which indicates that Tarsnap's target market is not very price-sensitive. If Tarsnap doubled its prices for new customers would the rate of new signups really drop by more than 50%?
