The decision was completely partisan 5-4 with 5 Republican appointees voting in the majority, 4 Democrats in the minority. https://www.oyez.org/cases/2008/08-205

Obama appointed 1 of the 4 Democrats who voted in the minority, his only appointee up to that point https://en.wikipedia.org/wiki/Barack_Obama_Supreme_Court_can...

So he literally did all he could, subject to the constitution, to prevent this ruling. The logic of mentioning Citizen's United here is like people complaining that abortion rights were taken away during Biden's term. In other words, there is no logic other than a crude misdirect.

So, if he were to want the decision, but also wanted appearances, he could oppose it verbally knowing he could do nothing to impact the outcome anyway.

Not to say that actually happened. Just pointing it out.
