The text of the LGPL actually imposes some very inconvenient restrictions around static linking:

Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.

In order to be compliant, you would have to also ship linkable object files of the proprietary application code alongside the executable.

I’m just looking forward to the meme subreddits becoming less outdated. Feels like 2017 in here
