● What It Is: NetShield is a tool that blocks ads, trackers, and malware. With the paid version of Proton VPN, it's more advanced, but it's good to request basic NetShield for free users.

● Why It's a Good Request: For free VPN users, we don't need to see ads or worry about tracking that slows down our browsing. With a simple NetShield, the browsing is smoother and safer than trackers.

"Hi Proton Team, it would be awesome if free users could have a basic version of NetShield for ad and tracker blocking. Even a lite version would really help improve privacy for free users!"

This is my most request a features because privacy and ad-blocking are its primary benefits, at least in a simple way.
