I worked on an open source software for a startup and now I am not their employee. I have developed an open source software in the same technology, serving the same purpose.
What can be legal implications of launching this software that will be in competition (indirectly) with my previous employer's software?
P.S. This software will be totally free (no direct income other than donations) and will be released in the same free software repository where many other software serving this same function exist (including that of my previous employer)
