Indeed - from the Azure Pipelines side of things, we started seeing a fair number of open source projects move some of their workloads over to us when we announced unlimited build minutes for open source projects. (I'm a PM for Azure DevOps.)
From my perspective, it's been interesting to see how people do. Some people bring all of their builds, of course, but some people split it up so that it's a mix of Azure Pipelines and Travis (or, of course, something else). Some people are bringing one or two platforms over - maybe they had Travis working as their build validation system, but it was doing Linux builds. So adding Windows builds with Azure Pipelines made sense. Or they wanted to do macOS or iOS builds, so they started building on our macOS build agents.
Anyway, I'm happy for Travis and I'm glad to see that they're excited about this acquisition. I can speak from first hand experience that running builds for open source projects takes a lot of resources. So I trust that this will help them make sure that they're in a position to continue helping out the open source projects and communities.
