The source you quoted shows nothing about 'Obama actively campaigning for politicians in other countries'. In fact it exonerates him of your charges.
The most recent US interference in a foreign election (quoted in your source) was in 2000, when Dubya was President. You could arguable attribute that to Bill Clinton, since the groundwork would have to have been laid earlier than 2000.
> In 2000, the U.S. spent millions of dollars in aid for political parties, campaign costs and independent media. Funding and broadcast equipment provided to the media arms of the opposition were a decisive factor in electing opposition candidate Vojislav Kostunica as Yugoslav president, according to Levin. “If it wouldn’t have been for overt intervention … Milosevic would have been very likely to have won another term,” he said.
Obama would come to power a full 2 terms later.

(Sorry to essentially say the same thing multiple times over, but hypocrisy is so engrained in our dna you need to forcefully call attention to it sometimes.)
That's really the danger of whataboutism, it basically asserts that any two actions must be considered morally equivalent, regardless of the intended aim. That is simply not the case.
The US has a history of campaigning (put politely) or interfering (more accurately) in foreign elections[1]. It's not really a partisan issue.
I suspect having other countries interfere in the US election, the bastion of democracy in the western world, has happened before. Just never so visibly.

No details as to the content of the ads have been revealed. One would think that if they were pro-Trump they would have mentioned that in the release.
