Casa as a company is incentivized to help our clients store their funds securely, both by keeping them safe from thieves and by preventing user error. Our users’ success is directly related to our commercial success or failure as a company. Open-source storage systems don’t have this incentive. They are usually created on a volunteer basis and have no personal stake in the success of their users.
We want it to be clear how we make money and we want our incentives to be aligned with the best interest of our customers. We charge flat, annual subscription fees for our services for this reason.
There is a saying in the software industry that if you aren’t paying for a product, then the product is you. “Free” services are inherently untrustworthy. They may change their terms down the line, in which case you don’t know the deal you are going to get. Or they collect and sell large amounts of invasive user data for ad targeting purposes.
