It might be possible that on an international TECHNOLOGY forum, a significant percentage of users know what 'VPN' (a tech thing) stands for and don't know what 'ICE' (a government office (off topic) of a single nation (limited scope)) stands for. Context matters. ICE isn't within either the regional or topical domains of common conversation on this forum.
Depending on one's technical background or interests, reading about ICE can refer to many things. in my case Internal Combustion Engine and In-Circuit Emulator.
I thought this was another article about cars - engines overheating after bad security update and nation actors (agents) install apps and VPNs in cars.
