tldr; mcaffee made a shit ton of sqlite files in the temp folder causing people to call the sqlite devs phone angrily. now they name all files etilqs to prevent this.
Text from the screenshot:
2006-10-31: The default prefix used to be "sqlite_". But then Mcafee started using SQLite in their anti-virus product and it started putting files with the "sqlite" name in the c:/temp folder. This annoyed many windows users. Those users would then do a Google search for "sqlite", find the telephone numbers of the developers and call to wake them up at night and complain. For this reason, the default name prefix is changed to be "sqlite" spelled backwards. So the temp files are still identified, but anybody smart enough to figure out the code is also likely smart enough to know that calling the developer will not help get rid of the file.
Oh, I thought that the temp files were named by the user. If that's not the case, that these are not databases created specifically by McAfee in the temp directory, then I'm not sure what the appropriate solution should be. Obscuring the file type and how the file is used from users is still a bad practice.
McAfee wrote a program that used the Sqlite library for database storage.
When going about its data storage business for McAfee's program, the Sqlite library was storing files in C:\temp with prefixes like sqlite_3726371.
Users see that and get angry, and bug the Sqlite developers.
Now probably when initialising the Sqlite library McAfee could have given it the location of a directory to keep it's temp files. Then they could have been tucked away somewhere along with the rest of the McAfee code base and be more easily recognised as belonging to them, but they didn't.
So because of a bit of careless programming on McAfee's part, Sqlite developers were getting the heat because the files were easily recognisable as belonging to them.
Because the Sqlite developers don't have control of what McAfee was doing, the most expedient way to solve the problem was to obfuscate the name a bit.
