They are, it's just in very rare circumstances (monitored public wifi + possibly unsecured connection, for example). Most people should do fine and thanks to https, public wifi is far less of a threat than it used to be (plus, some started blocking VPNs).
Essentially the only valid use of a VPN. That, or masking your location from other users online.
I find YouTube in my country is just filled with content being pushed because it's local to my country. Some VPN exit points have less local content pushing, which gives me more options. Eastern European content is really good, but also completely missing from American YouTube suggestions.
