I'm not sure if you're arguing in bad faith or you misunderstand how either the Obama app or how Cambridge Analytical got their data.
Obama's app was advertised as an app for the Obama campaign. People who used the app consented that the Obama campaign would get access to data about them and their friends. For better or worse (better for marketers, worse for the friends of these app users), this was all within how Facebook was expected to work.
Cambridge Analytica obtained similar data, but in a different way by breaking Facebook's TOS. A developer made an app, advertised as some kind of quiz, never saying that the data would be handed over to CA. Not only was the app developer not being up front about what the data would be used for, but they also broke FB's TOS [0] with its usage.
Plainly, there are key differences here beyond how it was heralded at the time (and it should be noted that even the article your provided shows Obama's data collection in both a positive and negative light).

I see no material difference here. People shared their data and it was used accordingly. This is how Facebook is expected to work. It's not like the Obama app had a big button that said "upload your friends list to Obama's database!". That was covertly done behind the scenes.
Irregardless, all Facebook users should assume all of their data is being sold and sliced and diced a million different ways.
The main point here is that the media has tried to turn CA in to a scandal while they very much did not do that for very similar actions Obama was taking.
You are misunderstanding, in that the person you are commenting on isn't referring to their data collection techniques. The point is that, once the data was obtained, both of the campaigns used it for microtargeting. The only difference, as you pointed out, is that CA obtained their data in a way that broke the TOS. But whenever the "scandal" is discussed, it almost entirely focuses on the fact that CA/the Trump campaign was targeting voters with propoganda and manipulating their opinions. Yet, in that aspect, the Obama campaign was no different, but it receives a pass.
