For reference, travis CI was sold to an investment company some time ago.
The strategy is 100% to not improve the infrastructure, fire all the developers to save costs, and milk money from existing customers for as long as possible.
Around that time and for that reason, I migrated all my personal projects to CircleCI. I did the same for my then employer's open source projects, but CircleCI was also a customer, so it was a pretty easy sell.
