How about some generic "how to not buy into a single ecosystem that will maybe screw you one day".

Most important is a personality that prevents you from doing things just like everyone else or this urge to always use the newest tech because it is sexy.

Also important is to be able to feel more pain and to have to work more to achieve a solution that follows this rule and to accept this.

Using Google etc. products is easiest and only people who are strong willed enough and maybe have more skills in IT (pro user instead of average user) can really be free.

Then separate it into personal and work because in the first sector you have an own choice whereas in the second one you will have to comply most of the times.

Also: Storing stuff in proprietary systems which does not provide an export capability (using an open format) is a bad idea - always.
