Hi @Mohammad . Breadcrumbs is rich snippet, that Google pick up from our websites or blogs. It does not impact on ranking anymore. May be you posted article before you understand it well.
Q. Does I lost permalink benefits in SEO?
A. Big NO. your permalink of site, is another thing, I appropriate your examples, but these type of sites do many mistake in technical SEO.
support.google.com using schema breadcrumbs because they does not using good permalink structure. When developer.google.com does not using rich snippet, because they have good permalink structure and navigation at top of the site. Just imagine your self How google can introduce new things, that impact less in seo?
If you notice wikipedia links in mobile phones, then Google pick up site navigation like breadcrumbs.
In case of blogger, breadcrumbs does not impact in SEO. instead it will give you more CTR in search results.
