You can't really predict the future if a large tech company will properly fund an open source project to reproduce what they have internally, and if that will be any good in time, especially if none of it exists. In the mean time, you need a solution to problem X. I've even written a few libraries like that, and still stuff out there isn't that good or does not exist years later, because it's too niche, yet still a generic issue in the industry. Can't open source it although. In an alternative timeline, Buck for example could of been the OSS solution that google decided to devote their resources to, and then in the end it would of been a good idea that FB created their own version of it.
