Future of Open Source
• The survey reports that 78 percent of its respondents are now
running their businesses with open source software, and two-thirds
are building software for their customers that’s based on open source
software.
• Twitter’s messaging app is a good example of how open source can
be powerfully used — and of how well-known companies are
influencing the community.
• We’re seeing companies like Twitter, Netflix, and Ericsson actually
willing to pay developers to participate in the OSS community, and
both develop and use open source in their own frameworks. With 55
percent of this year’s respondents also indicating that OSS helped.
