This is the point, FOSS is great for share, for devs for own projects, for collab.....but of course it is not what many say, FOSS is neither a guarantee of privacy, nor of security and, of course, many times of proper functioning. That is, for a normal user, without programming skills greater than Hello World, all this is not so relevant, he can't really use all the advantages which offers a accesible script nor modify it to his like or fork it, but if a product offers a good TOS and PP, which is not controlled by BigBrother, it works optimally for what he need it, have good support and maintenance, the latter also things where FOSS shines often as non-existent, that is to say that FOSS or any other software or service is only as good as the support community or the dev team behind it. The trustworthy of a soft or a service is based on much more as only a license type, that is only shown in the daily use and in the support and maintenance it receive.
