Fair points. Thankfully, I haven't had any of those issues.

I run GNU/Linux on all my personal computers but the Windows 10 laptop from work came with Bitlocker installed and other than entering the PIN on start-up, it stays out of my way. Granted, I'm not dual-booting, saving important documents or running any backup tools; I mostly use it for browsing, Teams calls and SSHing into my Fedora workstation and other servers after connecting via VPN.

Also, in my case, performance was only noticeably affected when the IT contractors installed Symantec anti-virus which resulted in the laptop becoming a noisy heater every so often.

For what it's worth, I bought my wife a laptop for her birthday when she needed a new one and I never considered enabling Bitlocker on it. She wouldn't have any sensitive data on it so I figured there's no need.
