The Internet is quite fine at delivering packages over encrypted channels which I can trust. (Except where interdicted by governments, like in China, India, Russia, Turkyie,..)

The Web is a rather different beast, but the question is not "can you trust the Internet", but "can you trust a random website", and now even "can you trust a previously trustworthy website".

You of course should not trust any pictures or videos as critical evidence, they should be corroborated by other means. But this has been true for several years now.
