It genuinely makes me a little anxious whenever I come across people whose entire digital lives are dependent on a google/apple account. Just one misstep and it's all gone
e.g. email on a custom domain. your domain registrar is now a spof AND your email provider for your domain is a spof. and that's just email.
There's obviously a middle ground and ways to have a strictly better personal data posture than before, but it's a multi faceted problem balancing usability, security, and resilience
