I don't know about others, but we chose to use Go despite the problems with the language itself because we liked several properties of the Go runtime. Particularly, the fact that Go is garbage collected (so it's memory safe), but has much lower memory and start time overhead than even the latest versions of Java or .NET or even Haskell; and the ecosystem is much greater than something like OCaml. This low overhead is very useful for a microservices-based application. For my team, we would have loved to have something like C# (or even Java), with generics, exceptions, lambdas, LINQ/Streams etc., but with Go's low overhead and large ecosystem. Go the language was a major negative point, just not bad enough to outweigh the advantages of the runtime.
