If you are referring to corporate "free" products such as email, cloud and media consumption, I use them until I'm able not to and switch to open source. ex. Gmail -> protonmail Google Drive, photos, contacts -> Next Cloud YouTube -> Jellyfin etc. If you're referring to corporate Social Media, I just refrain from using them, except FB at the minimum due to contact with old relatives. For other Social Media consumption, I ditched Tweeter (or X or whatever) and Reddit, never used Instagram and TikTok. Switched to Federated SM like Lemmy (Duh!!!) and Mastodon.
TLDR. I value my data,but I draw the line in accordance with my ability to afford it
