For someone already using OpenPGO encryption, to locate and ingest Proton user's public key is a problem that pales compared to what a Proton user must do in order to be able to communicate securely with (what they call) "external user", even when his or her public key is available via WKD and is on keys.openpgp.org.
In addition, it is almost axiomatic that that "external user" is probably not using "web-mail" but a mail-client on his computer (Thunderbird or equivalent) and is likely much more technically capable than the typical web-mail Proton user. The reluctance of Proton to automate importation of external user's public keys makes their claim of "OpenPGP interoperability" somewhat shallow. Increasing the number of e-mail users that encrypt their mail in general would probably increase their user population more than a minuscule number of current POP/SMTP mail users they hope to convert to web-mail use (and their service).
