@Charger8232 Lists from #Alternativeto (which this is based on) are usually not very reliable and show information that just isn't correct on a service or often includes services that are not real Alternatives to what you were looking for in the first place. The only thing that helps against that is doing your own research.
To pick out one example (I don't have time to them all): they list #Posteo as being proprietary which just isn't correct. That company is as #opensource as they come.
