Especially when you do this, considering a lot of privacy extensions are disabled by default in incognito mode (at least in FF), so there's less blocking of tracking elements.
(Also, unless you change your DNS provider or use a (proper) VPN, I believe your ISP sees everything no matter what, though I could be wrong about the latter.)
On the other hand, if this is a woosh situation & it's a joke, well, then, eh, I've seen funnier. ¯\_ (•_•) _/¯
This is only true if you set your browser that way. On firefox I have all extensions be able to work in incognito. I believe you can do this on chrome too but I don't use that.
