I don't mind losing out on bundled document editing apps, etc. by not giving my email money to Google or Microsoft, but I do wish the smaller providers saw email and calendars as two sides of the same service as I do. I use Migadu for email, but their calendar offering is still in beta and very primitive. So I use Fruux, to support a small open source company. But i've had support messages completely ignored by Fruux and the cost of paying for 2 micro services feels disproportionately expensive.
