I am still trying to get up to speed on this topic, which is obviously complex. However in respect of your article "ὁ κατέχων in 2 Thessalonians 2:6-7":
"For these reasons, we should reject the traditional three-phase interpretation– which posits a pre-
parousia outpouring of evil, and instead recognise that Paul is describing events which will take
place
(more or less) simultaneously – Satan will be removed, revealed and destroyed."
I have to say I find this appraisal incoherent: satan can't be said to have been "removed" if he is then immediately revealed.
There are other passages in the bible that seem to be related to the above that suggest that the final and full manifestation of satanic power will exist for a little while, a short while, or an "hour" - the Gk.
hora in Rev 17:12 (usually translated hour) is used variably in the NT (see
here) but originates in the idea of a season.
Also note Rev 20:3 - the one restraining demonic power for a 1000 years is the "angel coming down out of heaven" (Revelation 20:1). The ones "restraining" the truth in Rom 1:18 are the wicked, bu κατέχω is used in a contrary sense in 1 Cor 11:2, and 1 Cor 15:2 to mean "keep the Word/Faith." So κατέχω is highly contextual to the sentence in which it is used.

cf. Revelation 17:10 "They are also seven kings. Five have fallen, one is, the other has not yet come; but when he does come, he must remain
for only a little while."
cf. Revelation 17:12-14 "Kings who have not yet received a kingdom,
but who for one hour will receive authority as kings along with the beast. They have one purpose and will give their power and authority to the beast. They will wage war against the Lamb, but the Lamb will triumph over them because he is Lord of lords and King of kings."
cf. Revelation 20:3 "He threw him into the Abyss, and locked and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended. After that, he must be set free
for a short time."
