Of cause that is a BS reason. But they should have stopped using fax machines 20 years ago. How can any reason they give why they have to stop now be any other than BS.

In this case I think the renewables target is better. CO2 reduction is the goal, but having it as a single target can lead to lock-ins. Especially when the target is only low CO2 and not zero.

E.g. you could reach an 80% goal, while still expanding the use of fossil gas to replace coal and lignite. But we need a system that goes to 100% renewables by 2035. And first ramping up gas to then switch to renewables after is what got Germany in this mess.
