A central problem of contemporary physics is whether the law of gravity is non-Newtonian on galaxy scales. Rodrigues et al. argue that Milgromian gravitation, which solves the flat rotation curve problem without the need for dark matter particles, is ruled out at > 10�� significance. To a large extent, this conclusion relies on galaxies with very uncertain distances and/or nearly edge-on orientations, where dust obscuration often becomes significant. Applying appropriate quality cuts to the data leaves only a handful of outliers to the predictions of Milgromian gravitation according to the analysis of Rodrigues et al., but even these outliers can be explained with Milgromian gravitation.<br/>Author version, published in Nature Astronomy on 13.Nov.2018 (free version: https://rdcu.be/bbuvP) as a Correspondence to the article by Rodrigues et al. http://adsabs.harvard.edu/abs/2018NatAs...2..668R; see also McGaugh et al. for a parallel Correspondence (https://www.nature.com/articles/s41550-018-0615-9); for a reply by Rodrigues et al. see https://www.nature.com/articles/s41550-018-0614-x<br/>
