@Em0nM4stodon successfully migrated our UK based workers' co-op from Google Workspace to Infomaniak's ksuite (Swiss based) earlier this year and we're much happier (plus our bill is waaay lower). The ksuite also replaces Slack and Zoom, so more services for less money and all encrypted.
Our website is hosted independently in the UK. Newsletter is with EmailOctopus, a UK company.
Won't be sad if we lose Instagram tbh.
I guess we might be impacted indirectly if payment processors like PayPal and Stripe go down but we could find a work around.
Of course, these are all small business solutions and should be separated from personal or activist ones.
