I've been bitten multiple times by relying on external products, only for the vendor to either go bankrupt, or pivot, or get acquired and then prices exploded.

I've been bitten multiple times by relying on external products, only for the vendor to either go bankrupt, or pivot, or get acquired and then prices exploded. As a practical example, Heroku has been pretty unbearable support- and stability-wise since Salesforce bought them. But moving off their platform now that we integrated it into everything for 6 years is surprisingly difficult... Similarly, all of our Allegoritic automatons became worthless when Adobe bought them and replaced $100 once perpetual indie licenses with $250 monthly rental. I've abandoned custom 3ds max and vray plugins for the same reason. And ask anyone running a dropshipping store how renting their platform worked for them. Platform prices go up until you (the merchant) have practically no margin left.
