So much confusion about this. There was never a "vote" about it. It was more like a poll, which wasn't advertised across the EU, and on top of it was severely plagued by server failures. To have a binding vote:
- it needs to be properly announced to all eligible voters
- be declared as binding, you can't tell people it isn't a vote and later on declare it is
- the platform for voting needs to work
Who cares? On 26 March 2019 the European Parliament voted 410 to 192 in favor of dropping the DST requirement in the EU by 2021.
Nothing happend. All talk, no action, as I wrote above.
