Reading on computer screens damages your eyes. Plus long form reading is better on Kindle. So you should be sending your long articles to your Kindle and read them there. But Amazon's default Chrome extension does not work (see the recent reviews - https://chrome.google.com/webstore/detail/send-to-kindle-for-google/cgdjpilhipecahhcilnafpblkieebhea/reviews). Also a solution like KTool (https://ktool.io/pricing) is too expensive ($5-$10 per month) Create a solution that reliably works.
Use a small one-time payment model. Like $10 once.
