Probably a case of having engulfed the industry so much that just throwing money into the industry will actually pay out for them in the long run.

And it's probably also just nice to be able to bite Google and Microsoft in the butt here. Those do benefit from a healthy web and both very much need the PR of supporting webstandards, but they could also both benefit a lot more from controlling a platform like MDN and then sneaking in pseudo standards here and there. So, Samsung helping out with MDN makes it even harder for one of those to build up their own version.

Lastly, Samsung does ship their Samsung Internet Browser on all of their Galaxy devices, which has got to be a somewhat significant share of daily internet users. Currently, that's Chromium-based, but they could be looking to eventually follow Google and Microsoft in making up webstandards.

They've also already invested into Mozilla's Servo, so maybe they're also just trying to build up a partnership with Mozilla to help to take on those giants.

From what I've heard, Samsung Internet Browser is trying to lead the way with WebVR (Virtual Reality).
