Commentary
Hu dz is completely irregular. Abondolo (1996: 89) notes "phonological, semantic and cultural-historical difficulties", but does not treat the etymology in more detail and refers to EWUng (294-295). The Ugric etymology is also doubted by WOT (1273, 1318), but it is defended by Honti (2017: 78–81), who assumes that the affricate dz is secondary, and the word developed first from *ätV- via *äδV- to Hungarian ez- and secondarily to edz-. See Róna-Tas (2017: 61–62) for discussion of the problems with 16th century attestations. Róna-Tas (2017) stresses that dz is in any case irregular.
Even though the vocalism of the Ob-Ugric and Hungarian words could be regularly derived from *ä, the problem with the affricate makes the etymology implausible. No exact parallels to PU or PUg *t being reflected as *dz in Hungarian are known.
Conclusion
The Ugric etymology should be rejected.
