If I correctly understand the linked materials by Patrick Breyer [1], then the parliament (which is the piece of the E.U. where we are presently asked for our vote), is opposed to this pretty much in its entirety: It says "Parliament has positioned itself almost unanimously against indiscriminate chat control." So, it seems, the way you vote here doesn't much affect that outcome at all.
Also, if I correctly understand this table [2], then "Renew" (formerly "ALDE") is also opposed, so you don't need to adopt the leftist political ideology of the Greens as a package, just to get pro-privacy representation in the European Parliament. "Renew" does seem to be a viable "libertarian" alternative there. They also make some pro-privacy representations on their website. I don't follow European politics much, so I may be mistaken here. For example, I haven't looked into their voting record.
