And finally, there's a scale (see: threat models) - sometimes not leaking info or identity to some website / entity is enough, and there's no need to avoid to avoid state level actors, global passive adversaries, sophisticated timing correlation attacks and other funky creatures. Simplicity and ~zero maintenance (e.g. using some VPN with killswitch option) can be important factors in themselves.
