Don't get me wrong. I'm not against it if it is used in a proper way. But with all the programmer dudes out here: you should know best that you don't want someone else's software to force something on your computer. That is, yes, Malware.
I think it's fine if you allow your users a choice. So far, I have yet to see a website that does this. That's why I'm criticizing what is happening here.
bitp.it was designed as a background script that the user gets no knowledge of. Otherwise there would be some form of notification. There isn't. So this is bad, mhkay?
EDIT: I created a pillory thread in
this topic and it has already taken effect: bitp.it was removed from Detexify! So I guess even website owners see this is a bad idea.
