Some of them do.
In Poland most widely known is "Elektronika Praktyczna" (eng. 'Practical Electronics'), which is aimed at hobbyists and proffesionals alike. They have lots of technical articles, writeups on commercial and hobby projects (quite detailed, with theory of operation, schematics, pcbs and so on) but also quite a share of marketing (ads from vari ous distributors and manufacturers, sponsored contests where you can win devboards and such). They actually have engineers working for them, but also pay hobbyists and independent designers for published articles. Not all hope is gone.
