Nothing is inherently wrong but I trust my ISP a lot more than some random guys in Switzerland or Israel or whatever tax haven islands they operate from. They lie about what they’re good for which is just hiding things from my ISP. The rest of the benefits are fake
In the US ISPs collect, monitor, and sell your browsing history. https://arstechnica.com/information-technology/2017/03/how-i...
Because a secret you should know about your ISPs is they really don't care (or want to care) about what you are doing with their service. They don't want to add the hardware/software it'd take to spy on your data, that's a huge cost to them with nothing but downsides.
I might distrust a large ISP more just because they have the extra cache to burn. But a smaller more regional ISP will not try and invade your privacy.
I don't really, per se. Especially in my area where they have a monopoly. But VPNs aren't advertising making your home network safer anyway.
