it doesn't depend on time. the parliament can reject it every single time without it ever getting tired.
and since the MEPs represent the same people who elect governments who then delegate to the commission, it's strange if the commission continues to propose regulations that are unpopular.
the commission does what the member states want. obviously it has its own agency in the matters, but members don't send someone who would totally disregard their wishes.
the whole problem with these security-privacy ideas is that the member governments want to reign in the Internet, just as they did with every other phenomena for the past hundreds of years. (with varying degrees of "success".)
CSAM is especially a big red cloth that catches the eye of governments. It's not like there was less child abuse before the Internet, and if there were absolutely no CSAM on it from tomorrow ther wouldn't be less actual abuse... :/
