Well... yeah. He kind of is. The Syrian government's history of reconciliation is spotless. They intentionally try to make the reconciliation process as clean as possible so they can encourage more of it. They provide full amnesty to non-combatants and in almost every situation so far they incorporate the rebel fighters into the localised defense forces. The YPG had a similar ideology of treating POWs well in order to encourage more people to surrender knowing that they won't die or be mistreated if they do. That's one of the things that encouraged so many people to ally with the YPG and eventually form what is now the SDF.

Even the ones who do not want to reconcile are happy to jump into the green buses[0] and go to Idlib. They were happy because they knew they were safe. There were no extra-judicial murders, no retributions, no nothing.

If Bilal Abdul Kareem from OGN TV was able to leave Aleppo unharmed, why would aid workers be targeted?

This isn't some sort of conspiracy theory - it's just common-sense tactics for the Syrian government. It also doesn't mean that post-war there won't be retributions. I'm sure there will be. But there is no reason to suggest why aid workers would be high in that list when that same list contains some of the most deplorable extremist militia groups too.

Talking about the SDF is important, because the article is about what happens when the PYD leaves and the SyGov enters. And the answer is that nothing much will change, because SDF forces will just be rebranded to being SyArmy forces; they're going to take off SDF patches and wear Syrian ones. As has happened a dozen times before.
