Media companies oppose left candidates. Left candidates threaten the material interests of the owners of these companies, the ad buyers, the people who fund think tanks and establish or otherwise embed in academic programs like journalism schools.

The remainder is non-left candidates. These are people who work in those interests and therefore receive media support. For example, Reform UK gets inordinate neuteal or positive media coverage as well as volume compared to even the greens who are not much of a threat to capital.

These mass surveillance laws are a reaction to an failure in this overall apparatus to control thought and speech re: Gaza. They want to track and suppress and oppress information and speech that runs contrary to ruling class interests. The ruling class is heavily invested in the genocidal settler colonial project of "Israel" both literally with piles of cash and politically-strategically as a means by which to control and profit from political destabilization in parts of the Middle East.

Their explicit statements about why they want to do this are just a lie, a pretext. They are not personally or politically invested in protecting kids, lol. These are the people that protected Jimmy Saville and impoverished and made food insecure huge percentages of UK children.
