I am not sure how this made it to the front page or how you justify the click-bait.<p>- These are not paid opportunities for Open Source work. This a job board. The title makes you think that there are gigs to work on some open source projects and get paid for it.<p>- There are no guarantees that these "open source friendly" companies will hire you to work on Open Source. Working on Open Source projects is the exception, not the rule. Unless the company has gone the full OS model, which is just a few startups. And still, sometimes these companies have other kind of work (customization for a certain client) at which point you are not involved in the OS work at all.
