Reviews

I find the costs of Springer/Elsevier/Frontiers/MDPI and other commercial publishers unreasonably high. Sometimes, subscription fees are replaced by even more controversial publishing fees. I refrain from reviewing journal papers and I try to convince my co-authors not to publish at those venues.
There are at least in theoretical computer science very nice alternatives.

TheoretiCS (I already submitted three papers. One was rejected after one month. Last updated October 2023.)

Please let me know if you know of other open-access journals in theoretical computer science.
