It is totally reasonable to expect for-profit corporations to be good stewards of shared resources, such as the public goods that make up the Free and Open Source Software (FOSS) commons. I think it is important to all users of FOSS that the software is well maintained, and is able to grow to meet the changing needs of users. We often call achieving a system where sufficient value created by FOSS can be captured in ways that funds its ongoing development and maintenance achieving a "self-sustaining" system. One view on sustainability in FOSS can be found in this Apache Software Foundation blog post [1].

Companies should also be respectful of the communities that produce and maintain software, including understanding the philosophy and governance that communities have adopted. For the Apache Software Foundation, this is being mindful to not unduly influence the project, such as to try to control it through employing a majority of the people who work on the project, or otherwise weaken the independence and autonomy for the community that builds and maintains the software.

I've seen situations in the past where companies employ an open-source marketing strategy that ends up encouraging unhelpful activity in open source communities. This can also happen when companies measure the performance of a software developer based on metrics such as "number of patches accepted in an open source project." This kind of thing is generally unwelcome in open source software communities. See this thread on HN [3] on the Linux kernel development list, TL;DR - "Please don't waste maintainers' time on your KPI grabbing patches."
