this article is claimed to have multiple issues (POV, peacock, lack of sources, may not include all significant viewpoints) since 2018. At that time, there were indeed some formulations that were questionable in this respect, but they have been removed. In my opinion, also all other issues have been resolved and I'd like to remove the corresponding markers. Any objections? -- Qcomp ( talk) 11:20, 16 August 2021 (UTC) reply

since nobody objected, I removed the "multiple issues" template.-- Qcomp ( talk) 20:36, 23 August 2021 (UTC) reply
