I have read the whole article, translated with google, so some things might be lost in translation.
- The made shove and jump a bonus action, so that every char can have a bonus action each turn (personal opinion: This is bad, it makes some feats and class abilities useless)
- Surfaces and surface interactions are in the game (personal opinion: D:OS1 was still OK, D:OS2 went way too far)
- Armor system of D:OS2 is gone (personal opinion: YEAH

)
- They changes some other things to make things easier to understand. No details, he waits how players react to it. (personal opinion: Just stick to the DnD rules. DnD 5E is already easier to understand than the old games. Players are not idiots, at least I hope so.)
- You can avoid (almost?) every combat if you want by talking, sneaking and so on. (personal opinion: nice

)
- There is a reputation system, but no details yet.
- Game could take longer than divinity, partly because there are movie scenes and change of view during dialogue.
- You lose nothing if you do not select an origin char, because you can select a background for your custom char and characters will react to it.
- Tons of things will still change. They hope for lots of player feedback in early access.
- Game will collect data, like how much gold you spend and where do you die? (personal opinion: I hope you can turn it off)
I do not understand why devs want to make everything more simple. Are most players really so dumb that they do not understand the difference between an action and a bonus action, for example?
The UI must be clear about what you can do and what each stat, skill and ability does, thats it.
There needs to be a manual where the basics are explained. It should also mention the differences to the PnP rules.
If players do not want to read, why do they buy an RPG?
