Linux is used in many more contexts than OpenBSD. Moreover, unlike OpenBSD, Linux explicitly promises not to break userspace on new releases. So yeah, the Linux devs are more hesitant about anything that might be a user-visible behavior change.

OpenBSD never removed /dev/random - though they did remove arandom and prandom. But I'm not sure how your response explains the reasons for why they avoided OpenBSD's solution.

OpenBSD behaves like this patch, the article does a good job of describing what it has taken on the Linux side to get to this point and why IMO. In particular it wasn't until recently there was a reliable way to get quick randomness on nearly any machine to avoid blocking for long periods on boot which things had come to expect avoiding in the previous implementation.
