I'm not saying that what point out is not true, but telnet is prolly best compared to openssh, which is seems to be developed by 2[0] devs, and waaaaay more complex. Both are tools, both may be used for various over-the-network interactions with OSes.

It's an ad network. It has to deal with compliance in many regions. There are mobile apps.
